Biohybrid of elastic film and muscle cells packs a punch
In an innovative marriage of living cells and a synthetic substrate, bioengineers at Harvard University have found that a rubberlike, elastic film coated with a single layer of cardiac muscle cells can semi-autonomously engage in lifelike gripping, pumping, walking, and swimming.

Spray-dry vaccine for TB developed
Bioengineers and public health researchers have developed a novel spray-drying method for preserving and delivering the most common tuberculosis (TB) vaccine. The low-cost and scalable technique offers several potential advantages over conventional freezing procedures, such as greater stability at room temperature and use in needle-free delivery. The spray-drying process could one day provide a better…
